AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
324 PM CDT THU JUN 1 2006

.DISCUSSION...20Z SURFACE ANALYSIS PLACES A WEAK SURFACE COLD
FRONT ALONG I-44 FROM ST LOUIS TO OKLAHOMA CITY. VISIBLE
SATELLITE/WSR-88D TRENDS SHOW SCATTERED SHOWERS AND THUNDERSTORMS
ALONG AND AHEAD OF THE COLD FRONT IN THE WARM AND MOIST UNSTABLE
AIR MASS ACROSS THE LOWER MISSISSIPPI VALLEY. MAIN CONCERNS THIS
FORECAST PACKAGE IS CONVECTIVE POTENTIAL THROUGH FRIDAY.

TONIGHT...COLD FRONT WILL BEGIN TO MOVE ACROSS THE MID SOUTH
TONIGHT. ANY ONGOING CONVECTION SHOULD BEGIN TO DIMINISH IN
INTENSITY A BIT ACROSS THE MID SOUTH WITH THE LOSS OF DAYTIME
HEATING. 700-500 MB LAYER MID LEVEL LAPSE RATES WILL REMAIN WEAK
AROUND 6 C/KM ALONG WITH MID/UPPER LEVEL FORCING REMAINING FURTHER
NORTH ACROSS THE OHIO VALLEY. AS A RESULT...THINK THAT MOST IF
NOT ALL STORMS SHOULD REMAIN BELOW SEVERE LIMITS WITH INSTABILITY
DECREASING AS THE NIGHT PROGRESSES. BASED ON CURRENT CONVECTIVE
TRENDS WILL GO WITH SCATTERED POPS FOR THE EVENING HOURS WITH
CHANCES TAPERING OFF A BIT AFTER MIDNIGHT.

FRIDAY...A WEAK COLD FRONT WITH A TRAILING UPPER LEVEL TROUGH WILL
SLIDE THROUGH THE MID SOUTH DURING THE DAY ON FRIDAY. SHOWERS AND
THUNDERSTORMS WILL DEVELOP DURING THE DAY WITH THE MOIST AND
UNSTABLE ATMOSPHERE IN PLACE AND A SURFACE/UPPER LEVEL BOUNDARY
PROVIDING A LIFTING MECHANISM FOR ANY CONVECTION. EVEN WITH
MUCAPES AROUND 3000 J/KG AND LI/S AROUND -3...WEAK MID 700-500 MB
LAYER MID LEVEL LAPSE RATES AROUND 6 C/KM AND WEAK WINDS ALOFT
SHOULD KEEP MOST IF NOT ALL THUNDERSTORMS JUST BELOW SEVERE LIMITS.

FRIDAY NIGHT THROUGH SUNDAY...HIGH PRESSURE WILL BEGIN TO BUILD
BACK IN ACROSS THE FORECAST AREA. TEMPERATURES WILL BE AT OR JUST
SLIGHTLY BELOW CLIMATOLOGICAL NORMAL VALUES FOR JUNE WITH 850 MB
TEMPERATURES AROUND 13C SUPPORTING TEMPERATURES IN THE LOW/MIDDLE
80S.

MONDAY THROUGH THURSDAY...LONG RANGE UPPER AIR PATTERN ACROSS
NORTH AMERICA WILL FEATURE A BLOCKING RIDGE ACROSS THE WESTERN
UNITED STATES AND A TROUGH ACROSS THE EAST HALF OF THE COUNTRY.
LATEST 00Z GFS/EUROPEAN RUN STILL ADVERTISING BLOCKING RIDGE
TRYING TO TRANSLATE EAST LATE IN THE PERIOD. HOWEVER...AN UPPER
LEVEL CANADIAN LOW MAY DIVE INTO THE OHIO VALLEY KEEPING THE MID
SOUTH IN NORTHWEST FLOW ALOFT. WILL KEEP A SLIGHT CHANCE OF
SHOWERS AND THUNDERSTORMS IN FOR WEDNESDAY AND WEDNESDAY NIGHT AND
KEEP POPS OUT ELSEWHERE IN THE LONG RANGE FORECAST. &&
